NAZOV / TITLE : The Zeeman effect in stellar spectra ABSTRAKT / ABSTRACT : Main parameters of the Zeeman effect important for stellar spectroscopy is considered: normal and complex effect, longitudinal and transversal effect, Pashen-Back effect, magnetic sensitivity of spectral lines (Lande factors). The influence of magnetic field on the line profiles is demonstrated.
